When I last used an Android device (admittedly three years ago, but we are talking about "old" in this thread), the SIP support was part of the operating system - it was not provided by an app. For reference, the device was a Samsung Galaxy S4, but I suspect the SIP implementation and dialer integration was provided by Google, not Samsung.
Yes, finally found it. Noticed something weird - for outgoing calls, after the callee answers, the caller hears an unexpected ring tone. Probably means the caller may miss the callee answering the phone. Apart from that, it seems fine - so far. linphone also seems good, but on one phone (a One Plus 5) after receiving a phone call you have no receive audio. Not a codec issue, the same codec works for outgoing calls. linphone also reports it is sending/receiving audio fine at expected speeds. If you push the "video" button, the video fails, but audio comes good. Something to do with audio control on the phone I think. -- Brian May <brian@linuxpenguins.xyz> https://linuxpenguins.xyz/brian/
